Sept. 27, 1932. E. LULLAU I HoIsT 0R TRANSFER MECHANISM Filed Nov. 9. 1931 llll IL Patented Sept. 27, 1932 PATENT OFFICE ERNST LULLU, 0F BUFFALO, NEW YORK Hoism 0R TRANSFER MECHAN'ISM Application filed. November 9, 1931. Serial No. 573,889.

This invention relates'to a hoist or transfer mechanism designed primarily for handling loads into and out of buildings or from a lower to a higher level and'vice versa.

One of itsV objects Vis the provision of a mechanism of this character which is simple, kcompact and inexpensive in construction, which is efficient in operation and which can be easily and readily controlled with a minif mum of human effort.

Another object of the invention is to provide a transfer mechanism or load-handling apparatus which is designed for overhead suspension and which is provided with means for shifting the load-carrying element vertically or horizontally.

A further object has been to so design the apparatus that it operates with a minimum of friction and also that it can be compactly folded or collapsed so that it is out of the way when not in use.

In the accompanying drawing i Figure 1 is a side elevation, partly in section, of the transfer mechanism embodying my invention. Figure 2 1s a cross section thereof taken on line 2--2, Figure 1. Figure 3 is a similar section taken in the planeV of line 9J-e8, Figure 1.

Similar characters of reference indicate corresponding parts throughout the several views.

By way of example, I have illustrated my invention as installed in the cellar or basement of a. dwelling or building for facilitating the removal of ashes and other wasteV material therefrom, the numeral 10 indicating the cellar wall, 11 the side walk adjoining, 12 the window-opening, and 13 the ceiling joists of the cellar from which the operative parts of the transfer mechanism are susas to be capable of a linear movement to project the apparatus through the cellar window opening when in use and to retract the same into the cellar when not in use.

In the preferred embodiment of the invention shown in the drawing, 14 indicates a guide rail or track over which the load to be transferred isicarried7 the same being suspended adjacent one end for vertically swinging movement and connected on its opposite end to an elevator device for controlling such swinging movement. The track 14 is fulcrumed near its outer end to a horizontal pivot pin 15 suspended from a horizontally movable support lor carriage 16 engaging a guide member or rail 17 suitably fastened to one of the joists 13. This carriage may be of any appropriate construction so as to slide freely over the guide rail and depending from the same is a laterally swinging link 18 to the lower end of which is secured the pivot pin l5. At its opposite ends, the guide rail 17 is provided with stops 19 for limiting longitudinal movement of the carriage.

At its inner end the track 14 is operatively connected to an elevating device preferably consisting of a carriage or wheeled support 20 suspended from a cable 21 passing around guide wheels 22 attached to the joist 13 and connected at its inner end to a windlass 23 of any appropriate construction which may be mounted on the cellar wall or other appropriate support. Upon turning the windlass in one direction or the other, the track 14 is accordingly raised or lowered to the position shown by full lines and dotted lines in Figure l. The track is capable of longitudinal movement relative to the elevator-or wheeled support 20, and for this purpose said track is provided with a guide member or rail 24 freely slidable relatively to the support. Longitudinal movement of the track and its guide rail relative to the suppo-rt is limited by suitable stops 25.

Guided on the track 14 for movement lengthwise thereof is a load-carrying element or carriage 26 which is provided with a depending hook 27 for removably receiving a receptacle 28 in which the ashes or other material to be handled is carried. This hook is preferably pivoted at 29 to the carriage so as position shown by full lines in Figure 1 and permit the receptacle to drop by gravity to the floor or side walk. The extreme movement of the carriage 26 on the track 14 is limited by stop pins 31.

In the use of the apparatus, the track is lowered to the load-receiving position shown by dotted lines in Figure 1, and after the load has been attached to the carriage-hook 27, the windlass 28 is operated to elevate the track vto the forwardly-inclined position shown by full lines in the same ligure. When the track reaches this position, th-e carriage 26 with its load moves by gravity down the inclined track to a point outside the cellar, and when the load reaches the outer end of the track, it is automatically dropped onto the side walk in the manner previously described. After the contents of the receptacle 28 is dumped, it is again attached to the carriage-hook 27, and the track lowered to return the receptacle to the cellar. Vhen not in use, the track is drawn into the cellar and during this movement the outer track-suspension carriage 16 is free to slide in the guide rail 17 while the guide rail 24 at the inn-er end of the track is free to slide over the relatively stationary elevating carriage 20, the parts being shown in the retracted position by the substantially horizontal dotted lines in Figure 1. If it is desired to shift the transfer apparatus where it is out of the way and does not interfere with the head room of the cellar, the same may be swung as a unit to the position kshown by full lines in Figure 2, the link 18 constituting a shiftable hanger forthis purpose, and a hook and -eye 32 and 3.3 or like fastener is employed rfor detachably holding the apparatus in its collapsed position against the ceiling.

I claim as my invention 1. An apparatus of the character described, comprising longitudinally spaced overhead supports, a track fulcrumed at one end to one of said supports to swing vertically and suspended at its opposite end to the other support to move lengthwise thereof, a load-carrying element free to move longitudinally of the track, and means for raising and lowering said second-named track-support.l

2. An apparatus of the character described, comprising a pair of supports, one being movable in one plane and the other at substantially right angles thereto, a combinedv vertically swinging and longitudinally movable track suspended from said supports, and a load-carrying element movable lengthwise of said track.

3. An apparatus of the character described, comprising a pair of supports, one being movable in a substantially vertical plane and the other in a substantially horizontal plane, a track fulcrumed for vertically swinging movement on said horizontally movable support and suspended at its opposite end on said companion support for longitudinal Vmovement relative thereto and a load-carrying element mounted on said track for movement lengthwise thereof.

4. An apparatus of the character described, comprising a longitudinally movable overhead support, a vertically swinging track fulcrumed adjacent one end to said support and provided at its opposite end with longitudinal guidemeans, and a vertically movable support engageable with the guide means of said track, whereby the latter adapted to move lengthwise relative to said rei-Ji` cally movable support.

5. An apparatus of the character described, comprising an overhead guide member, a support movable lengthwise of said guide member, and a vertically swinging track fulcrumed on said support.

6. An apparatus of the character described, comprising an elevatable support, Va substantially horizontal overhead guide member, a second support movable lengthwise in said guide member toward and from said elevatable support, and a vertically swinging track fulcrumed at one end on said second support and slidingly connected at its opposite end to the elevatable support for. longitudinal movement relative thereto.

n 7. An apparatus of the character described, comprising a track, a laterally swinging pendant support to which one end of said track is fulcrumed for vertically swinging movement, and a vertically movable pendant support connected to the other end of said track.

8. An apparatus of the character described, comprising an overhead guide member. a support movable lengthwise of said guide member, a combined longitudinally movable and vertically swinging track fulcrumed adjacent one end to said support and provided at its opposite end with a guide member parallel to the. track, a flexible, vertically movable pendant support having means at its lower end engaging said track-bearing guide member, and means for actuating said flexible support to raise and lower the track about its fulcrum.
